Title:
METHOD AND DEVICE FOR TRANSMITTING POWER SAVING SIGNAL
Document Type and Number:
WIPO Patent Application WO/2019/196038
Kind Code:
A1
Abstract:
Disclosed are a method and device for transmitting a power saving signal, the method comprising: a network device sends a power saving signal to a terminal device, the power saving signal comprising a first sequence, the first sequence being used for indicating at least some of identifier information associated with the terminal device, and/or the first sequence being used by the terminal device to perform time-frequency synchronization, wherein the identifier information associated with the terminal device comprises the identifier of a device group to which the terminal device belongs, the device identifier of the terminal device, and physical cell identifier (PCI) information of a cell where the terminal device is located. Therefore, the power saving signal comprises a first sequence, and the design of the first sequence is associated with particular information of the terminal device, such as the device group to which the terminal device belongs, the device identifier of the terminal device, the PCI of a cell where the terminal device is located, and other information, such that terminal devices having different attributes can effectively identify their own power saving signals and perform corresponding operations according to the power saving signals.
